GRAIN-SEPARATOR.

To all whom t may concern:

Be it known that we, JOHN STADTHERR' and ALBERT BENGTsoN, citizens of the United States, residing at Gibbon, in the county of Sibley and State of Minnesota, have invented certain new and useful Improvements in GraineSeparators, of which the following is a specification, reference being had tothe accompanying drawings.

This invention relates to certain improve- `ments in grain separators and has relation I more particularly to a device of this general character of a gravity type; and it is an object ott-he invention to provide a separator of this general character having novel and improved means whereby wild peas or other substantially spherical foul matter vis readily separated from the grain. Y

It is also an object of the invention to provide a novel and improved device of this general character wherein the matter to be separated is caused to travel down an incline and wherein the lower or discharge end ot theincline is provided with meansfor imparting an upward movement or jump to the matter and which results in the wild peas or other substantially spherical foul matter being thrown a greater distance than the grain so that the requisite separation is etected.

The invention also has for an object to provide a device of this general character having novel and improved means whereby the matter to be separatedis subjected to a plurality of separating actions together with means whereby the separated grain and foul matter `are independently collected.

The invention consists in the details of construction and in the combination and arrangement o the several parts of our iinproved separator whereby certain important advantages are attained and the device is rendered simpler, less expensive and otherwise more convenient and advantageousfor use, all as will be hereinafter more fully set forth.

The novel features of the invention will hereinafter be definitely claimed. d

In order that our invention may be the better understood, we will nowproceed to describe the same with reference to the accompanying drawings, wherein- Figure l is a vertical sectional view of somewhat a diagrammatic character taken through a separator constructed in `accordspecification f Leners Patent.

Fig. 5 is a fragmentaryy view partly in section and partly in elevationv illustrating a tensioning member adapted toy be employedr in connection with each vof the endless carriers as embodied in the latter form of our As disclosed in the accompanying drawings,

C1 denotes a casing provided iii its top with the hopper H2 which discharges upon the top pan or member 4d. The ineinbers'td at their lower ends and at a predetermined point intermediate their lengths are provided with the upwardly directed'portions or irlangesQS. The upper iange or portion 23 of each of the pans or members @serves to throw the grain -upon the supplemental 'y pan or member 24; positioned above the pan pan or member 2% is also providedwith theA upturned portion or flange 25.

The vgrain as discharged tov each of thepans 4d and the coacting supplemental pan 24: is thrown upon the endless carrier 26 disposed oii a predetermined incline and having its upper stretch traveling in a direction toward the pan or member 4d. grain received upon the upper stretch of the carrier 26 is discharged by said carrier upon the apron 2T inclined toward and discharging upona second pan or member 4d and it is to be observed that the lower or discharge end of the apron 27 is provided with an upwardly directed portion or flange 28 whereb v a further separation ot the grain is effected. The portion oi ange Q8 serves to throw the foul matter against the shield or apron Q9 depending from the upper end portion of the pan or vmember 4d immediately above the apron 27. The aprons or shields 29 serve to deflect the foul matter within the collecting chamber B.

-From the foregoing description, it is thought to be obvious thata separator constiu'cted in accordance with our invention is' 'of an extremely simple and comparatively inexpensive nature and is particularly well adapted for use byreason of the convenience and-facility withwhich it may .and'it Willalso be obvious that our inven- ,be assembled,

tion'i's susceptible of some change vandmodi fication vwithout material departure from the principles and spirit thereof and for this reason lwe do not wish to be understood as limiting ourselves to the precise arrangement and formation of the several parts hereinl face of the lowerj stretch of' the 'expansible member shown in carrying out our invention in practicesexcept as 'hereinafter claimed.

We claim: Y 1. A device of comprising a plurality of inclined members discharging one upon the other, aprons depending from .the upper endv portions of certain of said members and endless ,carriers having their upperv stretches traveling toward the members, each of said endless carriers receiving from an upper inclined niember and delivering to an inclined member immediately therebelow. i

' 2. A device of -the 'character described comprising a plurality of inclined members discharging 'one upon the other, the lower ends of eac-h of said members being'disposed upwardly, aprons depending from the upper endportions of certain of said members and thel character described endless carriers having vtheir upper stretches traveling toward the members, each of said endless carriers receiving from an upper inclined member' and delivering to an inclined member immediately therebelow.

3. A device of the character describedl comprising a plurality of inclined members 'discharging one upon 'the other, and endless carriers having their upper stretches traveling toward'the members, each of said endless carriers receiving from an'upper inclined member and delivering to an inclined member .immediately therebelow.

In testimony whereof we hereunto aiix our signatures in the presence of two wit- 4nesses.
